IMPROVEMENT IN WINDOW-SCREENS.

Specification forming part of Letters Patent No. 167,100, dated August24, 1875; application filed July 17, 1875.

Y letters and figures of reference marked there- Figure l of thedrawings is a representation of a front view of my window-screen. Fig. 2is a vertical sectional view of the same, and Fig. 3 is ahorizontalsectional view thereof.

My invention relates to screens used in windows; and it consists in twoframes covered with wire-cloth, and having longitudinal grooves in theinneredges of the vertical rails, in which rails slide cleats or barsattached to the meeting-rails ofthe frames, as will be hereinafter morefully set forth.

In the annexed drawing, A and B represent two sashes or frames of anysuitable dimensions, covered with the ordinary painted wirelhe siderails of the two frames A B are, on their inner edges, formed each witha longitudinal groove,

a, and in said groove, on each groove, are inserted tenons b 1), formedon the ends of a bar,

D. The bar thus inserted in one frame is permanently secured to themeeting-rail of the other frame, thus holding the two frames together,and allowing them to slide one upon the other, while at the same timethe space between the two wirecloths is so filled at top and bottom ofthe junction of the two frames that no flies or insects can passin. Whenthe screen is made to fit the window from side to side the window may beraised more or less, as desired, and the screen extended or 0011-.tracted to correspond; or, if the window is wider than the screen, thelatter may be placed on its side and extended laterally till it fillsthe window.

What I claim as new, and desire to secure by Letters Patent, is-

The screens A B, having side rails provided with longitudinal grooves,a, on their inner edges, in combination with the bars D, at

tached to the meeting-rails of the screens,

and formed with tenons b on their ends to fit in the grooves,substantially as and for the purposes herein set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

GEO. W. HEIMBAGH.
